CMOS 1.8V / 1.5V Runtime SMARC HDA Audio signalling supports 1.5V or 1.8V.
Please check with your module vendor if 1.5V or 1.8V is
supported and use an audio codec that is capable to support the
regarding I/O voltage. This specification ignores the discrepancy
between the 1.5V and 1.8V signalling, as the chance of damage in
mismatched systems is negligible.
The SMARC HD Audio pins are shared with the I2S2 pins, which
are defined to be 1.8V only.
